Viral optical illusion asks if these legs are oiled or painted

The internet loves being baffled by deceptive photographs. The latest image to make the maddening rounds is this photo of a person's legs. Depending on you how you look at it, the legs are shiny with oil or simply smeared with some strategic slashes of white paint.

I'll admit I absolutely thought "shiny oily" the first time I saw the image. Just a few moments of study cured me of that reaction. It's a fun but fleeting optical illusion, but it probably will never rise to the level of dissent, despair and madness that surrounded The Dress.
